Fresh yeast, also known as pressed fresh yeast, contains a large amount of water, which needs to be preserved at low temperature for 3 months, and the dosage is 2-3 times of that of normal dry yeast.

Dry yeast can be stored for about 2 years after being dehydrated and dried.

Yeast is a kind of unicellular fungi, not a unit of phylogenetic classification. It is a general term for several families of unicellular fungi, such as ascomycetes and basidiomycetes. It can be used in brewing production, some are pathogenic bacteria, and it is a model organism for genetic engineering and cell cycle research. Yeast is the earliest microorganism used in the history of human civilization. It can survive in anoxic environment.

Yeast nutrition analysis:

1. Yeast powder is rich in vitamin B, and vegetarians often lack B1, B2 and B12, which can be provided in yeast powder;

Two Yeast is added to the dough. Under the temperature of 25-30 ℃, the yeast can easily grow the sucrose, glucose and fructose in the dough and the maltose converted from the amylase of the dough itself. A part of the sugar is decomposed into carbon dioxide and alcohol, which makes the dough immediately expand and start. Finally, a large number of vacuoles are formed in the bread and other foods, that is, the dough is soft and fragrant.

Guangxi yeast Biotechnology Co., Ltd. is a high-tech enterprise of dry yeast biological products. At present, the company's three major products: yeast α - amylase (special for sugar production), yeast promoter and acid free fermentation complex enzyme have been put on the market. Because it is an independent R & D product, the company has independent intellectual property rights, plus the particularity and high cost performance of the product itself, since it was put on the market, it has been praised by the majority of users. Guided by the application technology of enzyme engineering, the company has adhered to the road of independent research and development for many years. The three kinds of products are all applied in the fields of enzyme yeast cultivation and fermentation in sugar factory, starch alcohol production and sugar alcohol production. It has unique technical experience and technical route, and has developed the niche, high-tech and unique products to fill the market gap and meet the needs of users New products, out of a new path for the development of small and micro technology enterprises.

The company adheres to the concept of "relying on trees to enjoy the cool", and relies on each other with Jiangsu Boli Biological Products Co., Ltd., the leader of domestic enzyme preparation industry. The company is the entrusted processing unit of lecao products of Guangxi lecao Biotechnology Co., Ltd. The two enterprises learn from each other's strengths and seek common development.
